The data presented have been obtained in the course of long-term stationary quantitative studies on the annual seed reproduction dynamics of Siberian stone pine (Pinus sibirica Du Tour) stands, including the abundance of seedlings, and the local population of the nutcracker (Nucifraga caryocatactes macrorhynchos C.L.

Specific Features of Development of Megagametophytes and Embryos of the Siberian Stone Pine in vitro
Russian Journal of Developmental Biology, 2003Seedlings were grown in vitro from fertilized eggs and immature embryos of the Siberian stone pine. Cultivation of megagametophytes on a hormone-containing Murashige-Skoog medium from the egg formation until the globular embryo stage made it possible to manipulate fertilization and embryogenesis.

The structure of the crown and branching; the growth, development, and ontogeny of branches; and organogenesis and growth of female shoots in the model Siberian stone pine trees were studied in four types of habitats at the timberline in the central Altai Mountains (1700–2170 m a.s.l.).

The results of a karyological study on Siberian stone pines growing in the bog demonstrated differences from the populations of this species studied earlier with respect to sizes of chromosomes and location of secondary constrictions. The number of nucleolar organizer regions in the chromosomes of Siberian stone pine trees growing in the bog was larger

Chloroplast microsatellites and mitochondrial nad1 intron 2 sequences indicate congruent phylogenetic relationships among Swiss stone pine (Pinus cembra), Siberian stone pine (Pinus sibirica), and Siberian dwarf pine (Pinus pumila) [PDF]
Molecular Ecology, 2001 AbstractWe studied the phylogenetic relationships among the three stone pine species, Pinus cembra, P. sibirica, and P. pumila, using chloroplast microsatellites and mitochondrial nad1 intron 2 sequences. The three chloroplast microsatellite loci combined into a total of 18 haplotypes. Fourteen haplotypes were detected in 15 populations of P.

Assessment of Siberian Stone Pine Viability in the Introuced Plantations of Middle Volga Region
Vestnik of Volga State University of Technology. Ser.: Forest. Ecology. Nature Management, 2018Цель исследований заключалась в оценке жизненного состояния сосны кедровой сибирской по биометрическим и физиологическим показателям и определении их информативности для селекции устойчивых продуктивных биотипов. Приведены показатели роста культур в различных условиях, охарактеризована интенсивность фотосинтеза, установлены различия деревьев по ...

[Specific features of the development of Siberian stone pine megagametophytes and embryos in vitro].
Ontogenez, 2003Seedlings were grown in vitro from fertilized eggs and immature embryos of the Siberian stone pine. Cultivation of megagametophytes on a hormone-containing Murashige-Skoog medium from the egg formation until the globular embryo stage made it possible to manipulate fertilization and embryogenesis.
